As Dave mentioned...stick with the ships tours in Jamaica. We did the family White River tubing ...it was a blast. Our local guides were also giving us tips on who to watch for and whom to speak with. Grand Cayman was and extremly safe....did the Atlantis Sub ...very cool. My 2 cents....I'm a law enforcement officer here in Michigan near Detroit and the only time my little "caution alarm" went off in my head was in the side streets of Ocho Rios. Don't get me wrong.... just keep both eyes open. Both places were very beautiful.
